Jabsco Par-Max HD3 12V 3-GPM 40-PSI Water Pump

The Jabsco Par-Max HD3 12V Water Pump (part Q301J-115S-3A) delivers about 3 gallons per minute and shuts off at 40 psi. It is the heavy duty version of the 3 GPM Par-Max, built for longer life and steady pressure. The 40 psi setting suits older plumbing or systems with fixtures rated for lower pressure.

HD features include a heavy duty motor, cast aluminum lower housing, and co-molded diaphragm. An integrated bypass module reduces cycling and gives smoother flow at the tap. The pump self-primes from at least 7 feet dry and can run dry without damage.

Quick-connect ports make it easy to install and service. Vibration-dampening feet reduce noise transmitted through the hull. Fit a strainer on the inlet and protect the pump from freezing. Find the 60 psi version and larger HD pumps in our fresh water and washdown pumps.
